panther install issue

So i'm booting Panther from CD, i get to the login type window... it says "preparing installation..." and the blue and white bar is going accross the screen, it keeps doing this and never changes, does anyone have an explination?

i've got the latest firmware. I have a 6 Gig HD, i installed it on that with no problems. then i upgraded the RAM and HD, i got into the install then the CD drive broke... i got another CD drive that it'll boot from but it won't install for some reason, even if i just have the old 6 gig or just the new 80 Gig...
